PASADENA, Calif. — Although NASA’s Mars Laser Communications Demonstration never flew, the project proceeded far enough to establish a price for terminals to relay data for the Mars Telecommunications Orbiter: $90 million.In contrast, costs for NASA’s Laser Communications Relay Demonstration (LCRD) terminals were “on the order of $30 million” and the space agency is likely to pay $10 million to $15 million for Orion crew capsule laser terminals, said Bernard Edwards, LCRD chief engineer at NASA Goddard Space Flight Center. NASA’s TeraByte InfraRed Delivery, a cubesat to demonstrate optical links from the ground to low Earth orbit, will employ $100,000 terminals, he added.“The bottom line is the costs are coming down,” Edwards said May 21 at the Space Tech Expo here. “That’s what we have to do to make this realistic: get cost out of there.”Private companies are addressing that challenge and proving optical communications systems are ready for government and commercial applications, said Barry Matsumori, chief executive for BridgeSat, a company building a network of laser-equipped ground stations.Several companies including BridgeSat sell optical communications terminals or ground stations. Satellite communications service providers, meanwhile, are adopting the technology.Kongsberg Satellite Services is working with Tesat-Spacecom to ...
